the curb, its horse lying prostrate on the asphalt, its box
vacant of driver.
Harleston stopped. What had he here! Then he looked about for a
policeman. Of course, none was in sight. Policemen never are in sight on
Massachusetts Avenue.
As a general rule, Harleston was not inquisitive as to things that did
not concern him--especially at one o'clock in the morning; but the
waiting cab, the deserted box, the recumbent horse in the shafts excited
his curiosity.
The cab, probably, was from the stand in Dupont Circle; and the cabby
likely was asleep inside the cab, with a bit too much rum aboard.
Nevertheless, the matter was worth a step into Eighteenth Street and a
few seconds' time. It might yield only a drunken driver's mutterings at
being disturbed; it might yield much of profit. And the longer Harleston
looked the more he was impelled to investigate. Finally curiosity
prevailed.
The door of the cab was closed and he looked inside.
The cab was empty.
As he opened the door, the sleeping horse came suddenly to life; with a

the end of the search, was forced to grope in semi-darkness.
On the cushion of the seat was a light lap spread, part of the equipment
of the cab. The pockets on the doors yielded nothing. He turned up the
cushion and felt under it: nothing. On the floor, however, was a woman's
handkerchief, filmy and small, and without the least odour clinging to
it.
"Strange!" Harleston muttered. "They are always covered with perfume."
Moreover, while a very expensive handkerchief, it was without
initial--which also was most unusual.
He put the bit of lace into his coat and went on with the search:
Three American Beauty roses, somewhat crushed and broken, were in the
far corner. From certain abrasions in the stems, he concluded that they
had been torn, or loosed, from a woman's corsage.
He felt again--then he struck a match, leaning well inside the cab so
